Top: spectral analysis of the stellar parameters of HD 54236A, the eclipsing binary. Bottom: spectral analysis of the stellar parameters of the tertiary member, HD 54236B. The observed spectra for both HD 54236A and HD 54236B are shown in blue, while their respective templates modeled in green. Discrepancies between the target spectrum and its template are largely due to differences in flux calibration, however, spectral matching is done based on spectral features rather than overall shape.
